Press Release from the UK RAIB: Derailment at London Paddington station 25 May 2014
RAIB is investigating a derailment that occurred at London Paddington main line station, on Sunday 25 May 2014.
The train that derailed was an empty five car Class 360/2 passenger train (reporting number 5T08), manufactured by Siemens and operated by Heathrow Express. It was travelling from Old Oak Common to Paddington in preparation for entering passenger service.
At 05:20 hrs, both sets of wheels on the leading bogie of the third vehicle derailed to the left when the vehicle was about 150 metres from the buffer stops in platform 3 and travelling at between 12 and 14 mph (19.3 and 22.5 km/h).
The driver twice stopped the train after it derailed. On both occasions, unaware of what had happened, he restarted the train. As a consequence, the train ran nearly 100 metres in a derailed state and was finally stopped with the right side of the derailed bogie in a pit that was located between the rails, which lifted both wheels on the left side of the rear bogie off the rails. No one was injured.
Platform 3 remained closed for the remainder of the day.

RAIB’s investigation will examine the sequence of events leading up to the derailment and will seek to identify the causes. This will include consideration of the design, maintenance and condition of both the track and the derailed vehicle.
RAIB’s investigation is independent of any investigation by the safety authority (the Office of Railway Regulation).
RAIB will publish its findings, including any recommendations to improve safety, at the conclusion of its investigation. These findings will be available on the RAIB website.
